WebSeveral DNN based approaches have been proposed to improve ASR accuracy for far-field speech. In Miao and Metze (2015), bottleneck (BNF) features from a near/far field classifier were used together with regular acoustic features to improve far-field speech recognition. In the same work, the authors also proposed a novel Distance Adaptive WebNov 8, 2024 · For far-field ASR tasks, however, we are required to estimate RIRs from reverberant speech source signals independent of speaker and microphone characteristics. Recently, a neural network model was proposed to estimate the RIR from single-channel reverberant speech (FiNS) . The FiNS model directly estimates early RIR components, …

WebAutomatic speech recognition (ASR) is being widely deployed in many real-world … WebIn this paper we detail a data augmentation approach for far-field ASR. We examine the impact of using simulated room impulse responses (RIRs), as real RIRs can be difficult to acquire, and also the effect of adding point-source noises.
Webpublic dataset of far-field speech, it is more challenging to develop an ASR system in this field. Over the past decade, some progress has been made in addressing the challenges posed by far-field speech. For ASR, this improvement can be attributed to effective data augmentation [3], advances in speech enhancement [4] and E2E-ASR techniques ...
